Are Contact Prescriptions the Same as Glasses? Everything You Need to Know

November 27, 2024/in General Optometry /by 20North

No, contact prescriptions are not the same as glasses prescriptions. While both are designed to correct refractive errors and provide clear vision, they differ due to the way lenses interact with your eyes. Glasses sit about 12 millimeters away from the surface of your eye, whereas contact lenses rest directly on the cornea. This difference in positioning impacts the lens power and other prescription details.

Additionally, contact prescriptions require specific measurements—like the base curve and lens diameter—that ensure a proper fit and comfort when wearing lenses. These details are not included in an eyeglass prescription.

If you’re curious about why these differences matter or what makes a contact lens prescription unique, keep reading to get a deeper understanding. Properly understanding these distinctions is key to achieving the best vision correction for your lifestyle and eye health.

Key Differences Between Contact and Glasses Prescriptions

When it comes to vision correction, contact lenses and glasses may address the same vision problems, but their prescriptions are tailored differently due to how they interact with your eyes. Here’s a closer look at the main differences:

Refractive Error and Lens Positioning

Glasses sit approximately 12 millimeters away from your eyes, while contact lenses rest directly on the cornea. This proximity affects how lens power is calculated to correct your refractive error, such as nearsightedness or farsightedness.
Contact prescriptions often adjust the lens power to account for this closer placement, ensuring accurate vision correction.

Additional Measurements for Contact Lenses

Unlike glasses, contact lenses require extra specifications for a proper fit and optimal performance. These include:
Base Curve: Determines the curvature of the lens to match the shape of your eye.
Lens Diameter: Ensures the contact covers the cornea properly without causing discomfort.
Contact prescriptions also specify the lens brand, material, and expiration date, as these are medical devices designed for specific wear patterns.

Peripheral Vision

Contact lenses provide full peripheral vision, as they move with your eyes, unlike glasses which only correct vision within the frame area. This can make contacts preferable for activities like sports or driving.

Customization for Vision Needs

Specialty contact lenses, such as multifocal contact lenses or lenses for astigmatism correction, require detailed measurements to ensure precise correction and comfort. These details are unique to contact lens prescriptions and are not included in eyeglass prescriptions.

Understanding these differences highlights why you can’t interchange contact and glasses prescriptions. Each is specifically tailored to the type of lens and how it interacts with your eyes. For the best results, a comprehensive eye exam is essential to determine the right prescription for your individual needs.

Understanding a Contact Lens Prescription

A contact lens prescription includes specific details that are essential for ensuring the lenses fit your eyes comfortably and provide accurate vision correction. Unlike an eyeglass prescription, it goes beyond just lens power to address additional measurements unique to contact lenses. Here’s a breakdown of the key components:

1. Lens Power (Sphere)

This measures the strength needed to correct your vision, whether for nearsightedness or farsightedness.
It’s often marked with a minus sign for nearsightedness and a plus sign for farsightedness.

2. Base Curve (BC)

The base curve refers to the curvature of the contact lens, which ensures it fits snugly on the cornea.
An improper base curve can lead to discomfort or poor vision correction, making this a critical part of the prescription.

3. Diameter (DIA)

The diameter determines the size of the lens to ensure it fully covers the cornea while allowing for a proper fit.
This measurement varies based on the lens type, such as soft contact lenses or specialty lenses like multifocal contact lenses.

4. Lens Brand and Material

Contact lens prescriptions often specify the brand and material of the lenses, as not all lenses are made the same.
This ensures you get the right lens type for your needs, whether for daily wear, extended wear, or specialty purposes.

5. Additional Measurements

Some prescriptions may include values like pupillary distance or astigmatism correction parameters (e.g., cylinder and axis) for toric lenses.
These measurements ensure the contact lenses address more complex refractive errors effectively.

6. Expiration Date

Contact lens prescriptions have an expiration date, typically one year from the exam, to ensure your vision is regularly reassessed and your lenses remain safe for use.

7. Right Eye (OD) and Left Eye (OS)

Prescriptions include separate specifications for each eye, noted as oculus dextrus (OD) for the right eye and oculus sinister (OS) for the left eye, as vision needs often differ between eyes.

By including these precise details, a contact lens prescription ensures a proper fit and clear vision tailored to your individual needs. These extra measurements are what make contact prescriptions unique compared to eyeglass prescriptions. To get an accurate prescription, always schedule a contact lens exam with a qualified eye doctor.

Do You Need Different Prescriptions for Glasses and Contacts?

While glasses and contact prescriptions both aim to correct vision problems, there are situations where separate prescriptions are essential. Here’s why:

1. Lens Positioning Differences

Glasses sit further away from the eye (typically 12 millimeters), while contact lenses rest directly on the cornea. This difference affects how the lens power is calculated, especially for higher levels of refractive error.
For stronger prescriptions, even a small adjustment in lens power can significantly impact clear vision.

2. Eye Shape and Contact Lens Fit

Contact lenses require precise measurements such as base curve and diameter to ensure a proper fit. Glasses do not account for these factors because they don’t directly touch the eye.
A contact lens fitting ensures the lens conforms to the shape of your cornea and moves comfortably with your eye.

3. Vision Correction Goals

Contact lenses provide full peripheral vision, while glasses correct only the area within the frames.
For specific needs, such as multifocal lenses for presbyopia or toric lenses for astigmatism correction, separate prescriptions are necessary to address these conditions properly.

4. Different Usage and Lifestyle Needs

Some people prefer glasses for daily use but rely on contact lenses for activities like sports or special occasions.
These scenarios may require different prescriptions to accommodate varying vision correction and comfort needs.

5. The Importance of a Comprehensive Eye Exam

A comprehensive eye exam evaluates not only your refractive error but also your overall eye health and lifestyle needs.
Eye doctors use these findings to determine if you require separate prescriptions for glasses and contacts.

By understanding when and why separate prescriptions are necessary, you can make informed decisions about your vision correction. Regular check-ups with an eye doctor ensure that your prescriptions remain accurate and tailored to your individual needs, helping you achieve optimal vision correction in any situation.

What Prescription is Legally Blind? Understanding the Criteria and Causes

August 7, 2024/in General Optometry /by 20North

Legal blindness in the United States is defined as having an eye prescription of 20/200 or worse in the better eye with corrective lenses, or a visual field of 20 degrees or less.

Legal blindness is a specific level of vision loss defined by law to determine eligibility for certain services and benefits. It is important to note that being legally blind does not mean a person has total blindness; rather, it indicates a significant level of visual impairment.

Understanding the criteria for legal blindness is crucial for recognizing the severity of visual impairment. It helps in accessing necessary support, including disability benefits and specialized services designed to aid those with significant vision loss.

Criteria for Legal Blindness

Central Visual Acuity

Central visual acuity refers to the clarity or sharpness of vision when looking directly at an object. It is typically measured using an eye chart, technically referred to as a Snellen chart, which displays letters of decreasing size. The standard measure of normal vision is 20/20. Legal blindness is defined as having a visual acuity of 20/200 or worse in the better eye with corrective lenses. This means that while a person with normal vision can see from 200 feet away, a legally blind person can only see clearly from 20 feet away. If a person’s central visual acuity cannot be corrected to better than 20/200 with glasses or contact lenses, they are considered legally blind. This severe limitation impacts their ability to perform daily tasks that rely on clear central vision.

Visual Field

The visual field encompasses the entire area a person can see when looking straight ahead, including peripheral vision. Visual field tests measure the range of vision and detect any areas where sight is reduced or lost. Legal blindness can also be determined by a visual field of 20 degrees or less, often described as tunnel vision. Individuals with this condition have very limited peripheral vision, making it difficult to see objects not directly in front of them. Several eye conditions can reduce the visual field, including retinitis pigmentosa, glaucoma, and optic nerve damage. These conditions can severely restrict a person’s ability to navigate and be aware of their surroundings.

Common Causes of Legal Blindness

Eye Diseases Leading to Legal Blindness

Several eye diseases can lead to legal blindness by affecting either central visual acuity or the visual field. Understanding these conditions can help in early detection and management.

Macular Degeneration: This condition affects the macula, the central part of the retina responsible for sharp vision. It leads to a loss of central vision, making tasks like reading and recognizing faces difficult. Age-related macular degeneration (AMD) is the most common form and a leading cause of vision loss in older adults.
Diabetic Retinopathy: Diabetes can cause damage to the blood vessels in the retina, leading to vision impairment and, in severe cases, legal blindness. Diabetic retinopathy often progresses without early warning signs, highlighting the importance of regular eye exams for individuals with diabetes.
Glaucoma: This group of eye conditions damages the optic nerve, often due to high intraocular pressure. Glaucoma can lead to a gradual loss of peripheral vision, and without treatment, it can result in tunnel vision or even total blindness.

Other Factors Contributing to Legal Blindness

Beyond eye diseases, other factors can also contribute to significant vision loss that meets the criteria for legal blindness.

Retinitis Pigmentosa: A genetic disorder that causes the breakdown and loss of cells in the retina. This condition typically leads to a gradual decline in peripheral vision, night vision difficulties, and eventual tunnel vision.
Severe Refractive Errors: Extreme cases of nearsightedness or farsightedness can contribute to legal blindness if they cannot be corrected with standard prescription eyewear. These severe refractive errors interfere with visual acuity and the ability to perform daily tasks.
Accidents and Injuries: Traumatic events that cause significant damage to the eyes or optic nerve can lead to sudden and irreversible vision loss. These cases highlight the importance of eye protection in hazardous environments.

Living with Legal Blindness

Daily Life and Challenges

Living with legal blindness presents numerous challenges that affect daily activities and overall quality of life. Tasks that people with normal vision may take for granted can become significant obstacles.

Impact on Daily Tasks: Legal blindness can make it difficult to perform everyday activities such as reading, writing, cooking, and navigating unfamiliar environments. People with legal blindness often need to develop new strategies and use assistive devices to complete these tasks.
Assistive Devices and Visual Aids: To help manage daily activities, many people with legal blindness rely on various assistive devices and visual aids. These can include magnifiers, screen readers, braille displays, and specialized software that enhances contrast or reads text aloud. These tools can greatly enhance a person’s ability to live independently and maintain their quality of life.

Legal and Financial

Support Understanding the support available to those with legal blindness is crucial for accessing the resources needed to manage the condition effectively.

Disability Benefits: Individuals who are legally blind may be eligible for disability benefits through programs such as Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI). These benefits provide financial assistance to help cover living expenses and medical costs.
Financial Assistance: Additional financial aid may be available through various organizations and government programs designed to support those with vision impairments. These programs can help cover the cost of assistive devices, rehabilitation services, and other essential resources.

The Importance of Regular Eye Care

Maintaining regular eye care is essential for individuals with legal blindness to preserve their remaining vision and prevent further deterioration.

Routine Eye Exams: Regular eye exams are crucial for monitoring eye health and detecting any changes in vision. Eye doctors can provide valuable guidance on managing vision loss and recommend treatments or adjustments to assistive devices as needed.

Can Astigmatism Get Worse? Understanding Changes and Management

July 11, 2024/in General Optometry /by 20North

Can astigmatism get worse? The short answer is yes, it can change over time. These changes might depend on various factors, including age, health conditions, or even injuries to the eye. Understanding the nuances of astigmatism is essential for effective management and treatment.

Astigmatism is a common eye condition that affects millions of people worldwide, often resulting in blurry vision or distorted vision. Astigmatism originates from an irregularly shaped cornea or lens, which disrupts the focusing of light rays onto the retina. It can be present at birth or develop later in life, and while it often remains stable, certain conditions can cause it to progress or worsen. In this blog post, we will delve into the factors that can influence the progression of astigmatism, outline the symptoms to watch for, and discuss effective treatment options to maintain clear vision. Whether you’ve been living with astigmatism for years or have just noticed changes in your vision, gaining a thorough understanding of this condition is a crucial step toward ensuring the health of your eyes.

Understanding Astigmatism Symptoms: Basics and Beyond

$Astigmatism, refractive or refraction error. Eye disorder, eye does not focus light evenly on the retina. Blurry, blurred, or distorted vision. The illustration is isolated on a white background.$

Astigmatism is a type of refractive error where the eye does not focus light evenly onto the retina due to an irregular shape of the cornea or lens. This irregularity can lead to blurred vision, eye strain, and difficulties seeing at night. There are two main types of astigmatism:

Corneal Astigmatism: This occurs when the cornea, the eye’s outermost layer, is not perfectly round. Instead, it’s shaped more like a football, with one curve being steeper than the other.
Lenticular Astigmatism: This type involves irregularities in the lens of the eye, which can similarly distort vision.

Symptoms of astigmatism can vary but often include blurred vision, eye discomfort, and excessive squinting. Astigmatism is commonly diagnosed during a comprehensive eye exam, which includes a visual acuity test and a refraction test. These tests help eye doctors determine how light bends as it passes through your cornea and lens, indicating whether corrective lenses or other treatments are needed.

By understanding the basics of astigmatism and recognizing its symptoms, individuals can seek timely medical advice. Early diagnosis is crucial for managing the condition effectively and maintaining good vision health.

Treatment and Management of Worsening Astigmatism

Effective management of astigmatism involves timely intervention and suitable corrective measures. Here are the primary ways to treat and manage worsening astigmatism:

Corrective Lenses: Prescription glasses and contact lenses are the most common treatments for astigmatism. They work by compensating for the irregular curvature of your cornea or lens. Glasses with special toric lenses are designed to correct the way light enters your eyes, helping you see more clearly. Similarly, toric contact lenses provide a stable and comfortable option to correct astigmatism and can be customized to fit your eyes precisely.
Advanced Options: For those seeking a more permanent solution, refractive surgery can be an excellent option. Techniques such as PRK or LASIK surgery modify the shape of the cornea to permanently correct the refractive error. These procedures are highly effective and can reduce or even eliminate the need for glasses or contact lenses.
Regular Eye Exams: Because astigmatism can change over time, regular eye exams are crucial. These exams allow your eye doctor to track any changes in your vision and adjust your prescription or treatment plan as needed. Early detection of changes can prevent complications and help maintain optimal vision quality.

By using these treatments and committing to regular eye care, individuals with astigmatism can manage their condition effectively and enjoy clearer vision. Consult with your eye doctor to determine the best treatment options based on the severity and progression of your astigmatism.

Wipe Excess Sunscreen: Carefully wipe around your eyes with a soft cloth to remove any excess sunscreen. Avoid touching the eye directly to prevent additional irritation.
Flush Your Eyes: Hold your eye open under a stream of cool, clean water, or use a saline solution for at least 15 minutes. Blink regularly to help expel the sunscreen from your eye naturally.
Apply Eye Drops: After flushing, use lubricating eye drops that do not contain preservatives to soothe irritation. These drops can be applied every hour as needed to relieve discomfort.
Rest Your Eyes: Avoid using contact lenses and minimize exposure to bright sun for at least 48 hours after the incident to allow your eyes to recover fully. You can also apply a cold compress to constrict swollen blood vessels and relieve pain.

By following these steps, you can quickly address the discomfort of sunscreen in your eyes and get back to enjoying your summer safely. With those tips in mind, let’s hop into some other considerations for your eye health this summer!

Understanding the Risks of Sunscreen in Your Eyes

Sunscreen is vital for protecting our skin from the harmful effects of UV rays, but it can be a source of discomfort and potential harm when it gets into our eyes. Here’s what you need to know about the risks associated with sunscreen in your eyes and how to mitigate them:

Chemical Irritants: Many sunscreens contain chemicals like oxybenzone, avobenzone, and other active ingredients that can cause a burning sensation or temporary visual disturbance when they come into contact with the eye’s delicate tissues.
Allergic Reactions: Individuals with sensitive skin may experience allergic reactions not just on their skin but also in their eyes. Ingredients in some chemical sunscreens can trigger redness, swelling, and intense irritation.
Potential for Permanent Damage: While rare, prolonged exposure to certain sunscreen chemicals without proper rinsing can lead to more severe eye conditions, such as corneal abrasion or permanent damage to the eye’s surface. It is worth noting the Poison Control Center and the Food and Drug Administration have no documented cases of sunscreen causing permanent damage.
Protection Strategies: To minimize the risk, always apply sunscreen carefully around the eyes, use formulations labeled as non-irritating or designed for sensitive skin, and consider the use of physical barriers such as UV-blocking sunglasses and wide-brimmed hats.
Immediate Action is Crucial: If sunscreen does get into your eyes, immediate flushing with clean water or a saline solution is crucial to remove the irritant and reduce the risk of any long-term damage.

Understanding these risks and how to respond effectively can help ensure that your vision remains unimpacted as you enjoy the sunny days of summer.

How to Choose the Right Sunscreen for Eye Safety

Selecting the right sunscreen is essential not only for skin protection but also for preventing discomfort and damage to the eyes. Here are some preventative measures to ensure you choose and apply sunscreen in a way that keeps your eyes safe:

Avoid Spraying Near the Face: Never spray sunscreen directly on your face. Instead, spray it onto your hands and then apply it to your face to control the application and prevent it from getting into your eyes.
Supervise Children: Children are more likely to rub their eyes, so it’s important to supervise their sunscreen application. Apply sunscreen for them, ensuring it’s well away from a child’s eyes.
Secure Sunscreen Storage: Always keep sunscreen out of reach of children to prevent accidental contact with their eyes.
Thorough Application: Rub sunscreen in completely to prevent it from running into the eyes, especially if you sweat or swim.
Avoid Eye Area: Be cautious when applying sunscreen around your eyes. Consider using sunscreen sticks for a more precise application that’s less likely to spread into the eyes.
Wear Protective Eyewear: Large UV-blocking sunglasses will protect not just your eyes but also the sensitive skin around them from UV rays and accidental sunscreen exposure.
Choose Mineral Sunscreens: Opt for mineral sunscreens containing titanium dioxide or zinc oxide. These are less likely to irritate the eyes and are generally safer for sensitive skin types.
Look for Eye-Safe Labels: Some sunscreens are specifically formulated to be non-irritating and safe for use around the eyes. Look for products that are labeled as suitable for sensitive skin or are ophthalmologist-tested.

By following these preventative measures, you can enjoy the sun safely without compromising the health and comfort of your eyes.

Other Summer Eye Health Considerations

Summer is not only about sun protection; several other factors can impact eye health during the warmer months. Here are additional considerations to keep in mind:

Chlorine and Pool Water

Protection from Chlorine: Swimming pools can be tough on your eyes due to chlorine, which can strip away the tear film that protects your eyes, leading to dry eyes and irritation. Wear watertight goggles while swimming to protect your eyes from chlorine.
Post-Swim Care: Always rinse your eyes with fresh, clean water after swimming in a chlorinated pool to restore moisture and remove any residual chlorine that could cause discomfort.

Salt Water and Ocean Safety

Natural Irritants: Ocean water contains natural salts and biological matter that can irritate your eyes. Like with pools, wearing goggles while swimming in the ocean can prevent irritation.
Rinse After Swimming: Make it a habit to rinse your eyes with fresh water immediately after swimming in the ocean to remove salt and other irritants.

UV Exposure and Pterygium

Long-Term Sun Damage: Extended exposure to UV rays can lead to pterygium, a growth on the eyeball that can obstruct vision. This is particularly common among surfers and those who spend a lot of time in sunny, sandy, or windy environments.
Proper Eye Protection Measures: Wear UV-blocking sunglasses or a wide-brimmed hat that covers the entire eye area. Ensure your sunglasses meet the recommended UV protection standards to effectively shield your eyes from ultraviolet radiation.

Reflective Surfaces and Snow Blindness

Reflection from Surfaces: Water, sand, and other reflective surfaces can increase UV exposure dramatically, potentially leading to photokeratitis, also known as snow blindness.
Appropriate Eyewear: Use sunglasses with a wrap-around design to protect against UV rays coming from different angles. This is especially important in environments with high glare, such as beaches or snowy areas.

By taking these specific precautions, you can protect your eyes from common summer hazards and enjoy the season without compromising your eye health.

Do Night Driving Glasses Work

November 14, 2023/in General Optometry /by 20North

Night driving can be a demanding task, with trailing headlight glare, oncoming traffic, and limited light posing significant challenges. One solution that has been marketed for these issues is night driving glasses. These are special glasses, often featuring distinctive yellow lenses, that claim to reduce glare and improve contrast, making it easier to see when driving after dusk. Yet, an important question still stands: Do night driving glasses really work? Unfortunately, this simple question does not necessarily have a simple answer.

At Visionary Eye Doctors, we are a specialized team dedicated to providing stellar eye care tailored to individual needs and lifestyle goals. We strive to ensure your visual health and overall well-being are optimal. Our extensive expertise and utilizing the most advanced technology give us a unique perspective on eye-related matters, including the effectiveness of night driving glasses.

The following sections of this blog will illuminate how night-driving glasses function and evaluate their effectiveness based on available research. Our goal is to empower you to make informed decisions, navigating through diverse opinions and scientific studies regarding night-driving glasses.

Stay tuned as we delve into the science and research surrounding night driving glasses and their claims of enhancing your night vision and overall driving experience.

Understanding Night Driving

Let’s start by acknowledging the fundamental challenges that come with driving at night. It’s an entirely different ballpark compared to daylight conditions. Nighttime conditions are notably less optimal and there are specific issues that tend to arise only after the sun sets.

Night driving issues usually stem from external factors and personal eye health situations. Certainly, the blinding glare from oncoming headlights is one primary concern. Harsh lights from oncoming traffic easily disrupt your vision. The attack of bright lights against a predominantly dark backdrop can momentarily throw off your focus, causing a potential threat to your driving safety.

Moreover, the lack of adequate street light might cause poor peripheral vision. Add to that, the yellow hue from sodium-vapor lamps, predominantly used for street lighting, presents a unique challenge to discern obstacles on the road.

Now, let’s consider the inner workings of our eyes. Some individuals might experience night blindness, a condition that makes it difficult to see in low-light conditions. Factors that contribute to night blindness include inadequate adaptation to darkness, refractive error, and certain medical conditions, such as retinitis pigmentosa.

Furthermore, depth perception, an important aspect of safe driving, often gets compromised at night. Accurately judging the distance and speed of other vehicles becomes challenging in low-light conditions. This, coupled with eye strain and occasionally blurry vision from continuously adjusting to shifting light sources, makes night driving a strenuous task.

On top of these challenges, we must also consider blue light. Present in daylight and some artificial lighting, blue light scatters more easily than other visible light. This scattering makes objects appear less sharp and can contribute to glare, particularly in the context of oncoming headlights.

Getting a handle on night driving, with its myriad of challenges, is certainly not a walk in the park. It is in this context that night-driving glasses have been introduced to the market as a potential solution. In the next section, we’ll explore how night-driving glasses aim to counter these issues.

The Mechanism of Night Driving Glasses

Having established the issues associated with night driving, let’s shift our focus to the proposed solution: night-driving glasses. These specialized glasses often come with yellow-tinted lenses and claim to enhance visibility in dim environments. So how do these components function together to allegedly offer a better night driving experience?

A key feature of night driving glasses is the yellow tint on the lenses. The yellow tint is designed to filter out high-intensity, predominantly blue lights, by softening harsh lights and reducing the resultant glare. This blue light reduction can help decrease eye strain and improve general comfort when driving at night. Yellow-tinted glasses also aim to augment contrast in low light conditions, potentially enhancing depth perception and making it easier to distinguish objects on the road.

On the other hand, some night glasses come with clear lenses treated with anti-reflective coating, commonly referred to as ‘AR coating’. This coating is designed to minimize disruptive reflections on the lens surface, especially from oncoming headlights. With reduced reflections, drivers might find it more relaxed on their eyes, leading to a less stressful driving experience.

Whether they come with yellow-tinted lenses or clear lenses with AR coating, night driving glasses are available in both prescription and non-prescription versions. If you require corrective lenses for a refractive error, you can have your prescription incorporated into the design of night-driving glasses. Users who don’t need corrective lenses can opt for non-prescription glasses.

But does combining these elements in a specialized pair of glasses undoubtedly improve your vision when driving at night? After understanding the mechanism, it’s only logical to question its effectiveness. In our next section, we will evaluate the available research and studies concerning the performance of night driving glasses.

Evaluating the Effectiveness of Night Driving Glasses

With an understanding of how night driving glasses are designed to function, the next step is to assess the effectiveness of these glasses through various research studies and visual tests.

It’s important to note that despite their popularity, results from scientific investigations about their effectiveness are inconsistent. Some studies suggest night driving glasses can, indeed, help reduce glare and eye strain, making it more comfortable for individuals driving in low-light conditions. For instance, a certain fraction of trials demonstrate that these glasses can prevent temporary visual impairment caused by the bright light from oncoming headlights. This effect can translate to a better continuation of vision against such harsh light sources.

However, other researchers argue that the yellow-tinted lenses can potentially decrease visual acuity, especially in very low light conditions. Lenses with yellow or amber tints may improve contrast because they block scattered, blue light. Yet, they do so at a cost – the same tint also blocks some useful light, reducing overall light transmission to the eye. This reduction can potentially make your surroundings seem even darker, compromising visual clarity.

Lastly, the effectiveness of night driving glasses is also impacted by individual factors. For instance, refractive errors, if any, should be corrected with prescription lenses in night driving glasses for optimal performance. UV protection is another consideration. All eyewear, including night driving glasses, should block 100% of both UVA and UVB rays. High-energy visible (HEV) light produced by electronics and energy-efficient lightbulbs may be blocked with specially designed lenses for added protection.

In essence, the effectiveness of night driving glasses isn’t quite cut and dry; the answer lies somewhere in between, with ongoing studies and research aiming to provide a more definitive stance. To fully comprehend the potential benefits and limitations of these glasses, we recommend an in-person consultation with an eye specialist.

Recommendations from Visionary Eye Doctors

Night driving glasses have created quite a buzz with their claims of reducing glare and eye strain, and improving night vision. Their mechanism and components suggest progress towards a more comfortable night driving experience. However, the question, “Do night driving glasses work?” isn’t answered straightforwardly. While some studies and visual tests favor their usage, others highlight potential drawbacks and inefficiencies.

It’s important to remember that one size doesn’t fit all when it comes to visual health. What’s effective for one person might not be for another. Given the fluctuating evidence around the effectiveness of night driving glasses, it would be unwise to take them as a failsafe solution for night driving challenges.

If night driving is a concern for you, the best course of action would be to consult with your trusted eye doctor.

Visionary Eye Doctors, for instance, could provide you with a personalized solution, considering your age, medical history, visual acuity, and refractive error, among other factors.

In the realm of vision, a direct examination coupled with professional advice is steps ahead of a general product claiming universal effectiveness.

Presbyopia vs Myopia

September 26, 2023/in General Optometry /by 20North

Good vision is an indispensable part of our lives, impacting our learning, understanding, and daily interactions. When our visual acuity weakens, tasks that were once effortless can become challenging. Two of the most common refractive errors affecting numerous people are presbyopia and myopia. This blog aims not just to equip you with a comprehensive understanding of these vision problems but also to shed light on their effective solutions.

Presbyopia and myopia might seem intimidating health jargon, but let’s simplify. Myopia, most commonly known as nearsightedness, impedes your ability to see distant objects clearly, while presbyopia, frequently referred to as age-related farsightedness, hampers your clear vision of nearby objects. By throwing light on the distinguishing features of these conditions, this blog will make you well-versed in these vision problems and the comprehensive solutions we can offer.

At Visionary Eye Doctors, our passion for visual wellness drives us to deliver unparalleled patient-centric eye care. We leverage our medical expertise and state-of-the-art technology to address visual impairments, like presbyopia and myopia, ensuring an exceptional eye health experience tailored to your individual needs.

Understanding Myopia

Myopia, or nearsightedness, is a common refractive error that affects a large part of the population. In simple terms, someone with myopia can see near objects clearly but struggles with blurry vision when looking at distant objects. This happens due to the elongation of the eye resulting in light rays falling in front of the retina instead of directly onto it.

A critical concern about myopia is that it’s not just about blurry distance vision; it also carries with it risks for serious eye conditions like retinal detachment, especially for those with high myopia. The symptoms of this visual disorder usually begin in childhood, as the child may frequently squint or sit too close to the television. Other common signs include difficulty in reading the whiteboard at school, mistaking people or objects at a distance, and suffering headaches due to eye strain.

At Visionary Eye Doctors, we begin addressing myopia with a comprehensive eye exam. This helps us evaluate the extent of your myopia and formulate a plan to manage it effectively. If you or your child is grappling with these symptoms, we urge you to schedule an eye exam.

There is no one-size-fits-all approach for myopia control. Instead, there are numerous factors like age, lifestyle, prescription, and patient preference in choosing the correct solution. This could range from corrective eyewear in the form of glasses or soft contact lenses to more sophisticated solutions like laser eye surgery or monovision LASIK for suitable candidates. By accurately focusing light rays onto your retina, these treatments can yield clear vision across different distances, eliminating the undesirable effects of myopia.

Whether you prefer the convenience of wearing glasses or are inclined to the lasting results of refractive surgery, we ensure that you receive the most suitable solution for your condition. With us, you can trust that your vision is in the hands of experts who combine best practices with advanced technology to achieve optimal outcomes.

Delving into Presbyopia

An inevitable part of aging, presbyopia, often raises its head around the age of 40. Unlike myopia, presbyopia affects near vision, meaning that your eyes struggle to focus on close objects, which can make activities like reading or sewing a challenge. This natural condition stems from the gradual loss of flexibility of the crystalline lens inside our eyes, disrupting our clear vision.

Presbyopia typically presents a unique set of symptoms, easily noticeable during daily routines. You might find yourself holding your phone or book at arm’s length to read the text clearly or experience eye strain, headaches, and fatigue after doing close-up work. Sudden difficulty in reading small print, especially in low light conditions, is also a common sign of presbyopia.

We understand the impact of these vision changes on your life. Our services encompass comprehensive eye exams that allow us to examine the health of your eyes and detect presbyopia. If you’ve been experiencing these symptoms, we encourage you to confront them by scheduling a comprehensive eye exam.

Our presbyopia solutions range from reading glasses to multifocal contact lenses and refractive lens exchange. Reading glasses provide a simple yet effective method to counter presbyopia by providing magnification for close objects. However, if you’re already wearing corrective lenses for myopia, multifocal or bifocal contact lenses may prove to be a more seamless solution by allowing you to see across different distances through one lens. For those seeking a more permanent solution, refractive lens exchange might be an appropriate route. This procedure involves replacing the stiff crystalline lens with a synthetic lens that restores near sight.

Regardless of the solution that suits your lifestyle and vision requirement, you can trust Visionary Eye Doctors to offer personalized care and the latest technological solutions to meet your needs.

Comparing Presbyopia and Myopia Treatments

Now that we’ve unpacked the individual nature of both presbyopia and myopia, let’s cast our eyes on how their treatments align and differ. While glasses and contact lenses serve as common solutions for both, depending on individual needs and situations, one may consider more advanced treatment options.

LASIK surgery reshapes the cornea and corrects its focal point, providing a common solution for both conditions. For myopia, LASIK helps focus light on the retina, thus improving distance vision, whereas, for presbyopia, a practice known as monovision LASIK can be utilized where one eye is corrected for distance vision and the other for near vision.

Multifocal lenses are another shared solution for both presbyopia and myopia. By providing different lens powers for near, intermediate, and distance vision, these corrective lenses provide a seamless transition between varying distances. For myopia, multifocal lenses may also help slow down the progression of the condition in children.

As we explore these various solutions for vision correction, we underline that prescriptive decisions always rest on individual implications. Different methods may work best under different circumstances, and our team of experienced eye doctors is here to guide you along the way to make the best choice for your eyes.

Pink Eye vs Scratched Cornea: Understanding the Differences

August 28, 2023/in General Optometry /by 20North

Every blink, every gaze, every tear – our eyes tell stories that words often cannot. But, what happens when that story is interrupted by discomfort, redness, or even pain? Two common culprits often come to mind: pink eye and a scratched cornea. Although they might share a few overlapping symptoms, the causes, treatments, and implications of each are significantly different.

Now, if you’re finding yourself rubbing your eyes a bit too often, or waking up with that crusty, unpleasant sensation, you may be wondering: is it pink eye or a scratched cornea? Making an accurate self-diagnosis can be tricky, but getting it wrong can delay proper treatment and, in severe cases, lead to further complications.

At Visionary Eye Doctors, we are a leading name in ophthalmology and optometry. With a combination of advanced technology and a gentle, patient-first approach, our team has been at the forefront of corneal care, helping countless patients move past distress to relief. And today, we’re here to share some of that expertise with you.

Pink Eye: Causes, Symptoms, and Treatment

Pink eye, medically known as conjunctivitis, is an inflammation or infection of the thin membrane that lines the inside of the eyelid and covers the white part of the eye.

Pink Eye Causes

Bacterial Infection: Often caused by the same types of bacteria responsible for staph infections or strep throat, bacterial conjunctivitis can be quite contagious and usually results in a thick discharge or pus from the eye.

Viral Infection: Viral conjunctivitis, sometimes also known as viral pink eye, is frequently linked to common viral upper respiratory infections, like the flu or common cold.

Allergic Reaction: Allergic conjunctivitis happens when the eyes react to allergens in the environment, such as pollen, dust mites, or certain chemicals in makeup or contact lens solutions. This form is not contagious and often occurs seasonally.

Pink Eye Symptoms

Though it’s essential to consult an eye doctor for a definitive diagnosis, here are some tell-tale signs of pink eye:

Redness in one or both eyes
Itchy eyes, especially in allergic conjunctivitis
Watery eyes or a clear, thin discharge
A gritty feeling in the eye
Light sensitivity
Swelling of the eyelids

In cases of bacterial pink eye, symptoms can also include:

Green or yellow discharge from the eye, often making the eyelids stick together upon waking up
A runny nose or accompanying ear infection

Pink Eye Treatment

The treatment for pink eye depends on its cause. For bacterial conjunctivitis, your healthcare provider or eye specialist may prescribe antibiotic eye drops or ointments. Within just a few days of starting this treatment, symptoms often improve significantly.

On the other hand, viral conjunctivitis doesn’t have a direct treatment. Much like a common cold, it must run its course, which could be anywhere from several days to two weeks. However, some over-the-counter eye drops might alleviate symptoms.

For allergic conjunctivitis, one can employ artificial tears to dilute the allergen, antihistamine pills, or even specific prescription eye drops to reduce inflammation and discomfort.

No matter the type, if you suspect you have pink eye, it’s imperative to see an eye doctor to ensure you get the proper treatment and guidance. Remember: your eyes are delicate, and there’s no room for false self-diagnosis.

Scratched Cornea: A Closer Look at Corneal Abrasions

The cornea is a clear, protective outer layer of the eye. It acts as a barrier against dirt, germs, and other particles that could harm the eye. A scratch or injury to this sensitive structure is known as a corneal abrasion or corneal scratch.

Scratched Cornea Causes

Several events or objects can cause corneal abrasions:

Foreign Object: Something as small as a speck of dust, sand, or an eyelash can scratch the cornea if it becomes trapped under the eyelid. In more severe cases, larger foreign bodies like wood shavings or metal fragments can cause significant damage.
Contact Lenses: Improper use of contact lenses, whether it’s wearing them for too long, not cleaning them correctly, or using damaged lenses, can cause corneal scratches.
Physical Trauma: Accidental poking of the eye, rubbing the eye aggressively, or animal scratches are common physical causes.
Chemical Irritants: Exposure to some chemicals, even certain types of saline solution or clean water in large quantities, can lead to corneal injury.

Scratched Cornea Symptoms

The symptoms of a scratched cornea can be distressing. They include:

Sudden onset of pain and a gritty feeling in the eye
Redness and tearing (watery eye)
Blurred vision or vision problems
Sensitivity to light
The sensation of having something in the eye

Scratched Cornea Treatment

Timely treatment of a corneal abrasion is vital for proper healing and to prevent complications such as infection. Common treatment plans include:

Foreign Body Removal: If a foreign object is causing the abrasion, an eye doctor will typically use a fluorescein dye to highlight the object and then safely remove it

Antibiotic Drops: To prevent bacterial infection, an eye specialist might prescribe antibiotic drops.
Lubricating Drops: Over-the-counter artificial tears or lubricating eye drops can soothe the eye and assist in the healing process.
Avoid Rubbing: It’s crucial to avoid rubbing the eye as this can exacerbate the injury.
For larger abrasions or if there’s a concern about a corneal ulcer or deeper injury, more intensive treatment, or even a corneal transplant, might be required.

Always remember, if you suspect a scratched cornea, prompt attention from an eye care professional is paramount. At Visionary Eye Doctors, we’re equippedwith advanced technology to help diagnose and treat various eye conditions, ensuring your vision remains clear and healthy. You can even visit our state-of-the-art Corneal Care Center to meet with some of the best corneal specialists in the United States!

Pink Eye vs. Scratched Cornea: Additional Differences

At a glance, both pink eye (conjunctivitis) and a scratched cornea (corneal abrasion) can present with redness and discomfort, but understanding the differences can be vital. Let’s break down some more distinctions:

Duration and Progression:

Pink Eye: Symptoms of viral conjunctivitis can last from one to two weeks. If caused by a bacterial infection, it might resolve within several days with proper antibiotic treatment.

Scratched Cornea: Most minor corneal abrasions heal within 48 to 72 hours. However, deeper or larger scratches might take longer.

Complications:

Pink Eye: When untreated, especially bacterial conjunctivitis, can lead to more severe eye infections.

Scratched Cornea: Risks include bacterial ulcers, recurrent corneal erosions, or vision problems if not addressed.

Remember: The eye is a delicate organ, and self-diagnosis can be risky. Always consult with an eye doctor or healthcare provider like Visionary Eye Doctors for a proper diagnosis. We are here to provide expert care, ensuring you get the right diagnosis and treatment for your condition.

Preventive Measures

Protecting your eyes from injury and illness is paramount. Here’s a roadmap to ensure optimal eye health:

Prevention for Pink Eye:

Hygiene: Regularly wash your hands with soap and clean water. Avoid touching your eyes unless your hands are clean.
Avoid Contact: If you or someone you know has pink eye, limit close contact to prevent its spread. This includes abstaining from sharing personal items like towels or makeup.
Allergy Management: If you suffer from allergic conjunctivitis, understanding your triggers and managing allergens can be a game-changer. This might include using allergen-reducing pillowcases or staying indoors during high pollen counts.

Prevention for Scratched Cornea:

Protective Gear: If engaging in activities that pose a risk of foreign objects coming into contact with the eye, such as woodworking or certain sports, always wear protective eyewear.
Contact Lens Care: For contact lens wearers, ensure you follow the recommended cleaning routine. Always wash your hands before handling your lenses.
Artificial Tears: Use lubricating eye drops or artificial tears to combat dry eye, which can increase the risk of abrasions.
Consultation and Regular Check-ups: Routine visits to your eye specialist can preempt many eye-related issues. They can provide personalized advice based on your health profile and ensure that potential problems are detected early.

Closing Thoughts

While conditions like pink eye and scratched cornea are common, understanding the distinctions and seeking timely care can make all the difference. At Visionary Eye Doctors, we’re committed to ensuring that your sight remains clear and healthy. Our advanced technology and compassionate care form a holistic approach to eye health, from preventive measures to treating the most intricate of corneal issues.Should you ever find yourself faced with eye discomfort or other vision problems, remember to prioritize your health and consult a trusted healthcare provider.

Astigmatism vs Myopia

August 1, 2023/in General Optometry /by 20North

Astigmatism and myopia are two of the most common vision problems. There are similarities and differences between these two conditions, but they can also occur simultaneously. Known as refractive errors, both eye problems impact how your eyes focus light. It’s essential to know the difference between the two so that you fully understand your eye care needs.

While we can correct astigmatism and myopia with contact lenses and eyeglasses, they require different types of corrections. Astigmatism requires vision correction with cylindrical power. Laser correction surgery can typically assist with both vision problems, depending on the severity of your condition. When you understand the difference between astigmatism and myopia, you can take an active part in your eye health.

If you notice symptoms that include eye strain, headaches, and blurry distance vision, see one of our experienced eye doctors for an accurate diagnosis and treatment options. At Visionary Eye Doctors, your eye health and overall well-being are the main focus of our practice. Let us help you maintain clear vision for a lifetime.

Understanding Astigmatism

Astigmatism occurs when your cornea, which is the front surface of your eye, has an irregular shape. An irregularly shaped lens can also cause astigmatism. If you have astigmatism, your eye bends light in various directions instead of focusing light on a common point. You may experience eye strain, headaches, and poor night vision, as well as blurry vision at near and far distances. Many people are born with astigmatism which may be accompanied by farsightedness or nearsightedness (myopia).

Early diagnosis is key. That’s why it’s essential to schedule comprehensive eye exams. You should also contact our eye experts whenever you have a question about your vision. During your examination, you’ll receive a variety of tests to evaluate how your eyes bend light. Bright lighting and prescription contact lenses or eyeglasses can compensate for astigmatism, restoring clear vision. Laser correction surgery provides a more permanent solution, and most people can benefit from LASIK for astigmatism.

Understanding Myopia

Myopia is commonly referred to as nearsightedness. An elongated eyeball or curved cornea interferes with light rays entering the eye. This causes light to focus in front of the retina, so far objects appear unclear. However, you may clearly see near objects. Symptoms include squinting, eye strain, and headaches. This condition typically appears in childhood and may worsen as you grow older.

Treating myopia early can help prevent vision-threatening problems that may develop as you age. So, bring your children in for regular eye exams and schedule appointments to safeguard your eyesight. Your eye doctor will examine the structures of your eyes and test your vision to diagnose astigmatism, myopia, and other refractive errors.

Differentiating Astigmatism and Myopia

The visual characteristics of astigmatism and myopia differ based on how severe the condition is. However, they do share some common symptoms. While people with astigmatism have blurry vision at every distance, myopia typically does not impact near vision.

At the same time, both conditions cause eye strain and headaches. However, astigmatism may make night driving harder while myopia makes it difficult to see the whiteboard in school. Another key difference is that astigmatism requires eyeglasses or contact lenses with cylindrical power. Myopia requires vision aids that compensate for refractive errors.

Treatment Options for Astigmatism

Our team can typically treat astigmatism with eyeglasses, contact lenses, or refractive surgery.

Eyeglasses for Astigmatism

Eyeglasses with corrective lenses make up for an unevenly shaped eye. The lenses bend light so that it focuses on the retina. Some people prefer eyeglasses to contact lenses because they feel they are more comfortable and easier to use.

Contact Lenses to Treat Astigmatism

Like eyeglasses, contact lenses can correct most astigmatism. Toric contact lenses are designed to address astigmatism and are the most common type used to restore vision for this condition. The special shape of these lenses corrects for a misshaped lens or cornea.

You may opt for rigid contact lenses designed to correct the curvature of the eye. This process is called orthokeratology. Gradually, you’ll wear the lenses less often as your eye shape evens out. However, discontinuing the treatment may result in recurring refractive errors. Additionally, orthokeratology is more suited for mild to moderate cases of astigmatism.

Many people prefer contact lenses because they don’t want the inconvenience of wearing glasses. You may also prefer the look of contact lenses, which aren’t noticeable. However, it’s important to avoid wearing contact lenses for extended periods and use proper hygiene to store and clean them.

Ask your eye doctor about the pros and cons of contact lenses versus eyeglasses to treat your astigmatism.

Astigmatism Refractive Surgery

Our eye surgeon uses a laser beam to reshape your cornea and reverse the refractive error associated with astigmatism. You’ll undergo a thorough evaluation to determine whether you’re a good candidate for refractive surgery and which procedure would work best for you.

Here are the different kinds of surgery for astigmatism:

Laser-assisted in-situ keratomileusis (LASIK). Using an excimer laser, our eye surgeon will make a hinged flap in the cornea and then sculpt the cornea to the appropriate shape.
Photorefractive keratectomy (PRK). In this procedure, the protective cover is removed before the surgeon reshapes the cornea. The protective cover grows back naturally.

Treatment Options for Myopia

Eyeglasses and contact lenses are the primary methods of correcting myopia. However, there are also surgical options, including LASIK, PRK, and implantable lenses. Your eye doctor can help you determine the best method for your vision and lifestyle needs.

Eyeglasses for Myopia

Glasses are an effective solution to correct myopia. When you wear prescription eyeglasses, they change how light hits the retina to correct refractive errors. Eyeglasses are an ideal solution for children and adults with myopia and your eye doctor can provide a prescription following a routine eye exam.

Contact Lenses to Treat Myopia

Using the same vision tests, your doctor can provide a prescription for contact lenses that change the way light enters the eye. Contacts float on the surface of the cornea aided by your eye’s natural lubrication. Since they are set so close to the eye, they’re much thinner than glasses.

There are many types of contact lenses used to correct myopia:

Soft lenses are made of flexible plastic material. They cover the iris, pupil, and some of the sclera (the white part of the eye). There are many options, including daily and weekly lenses you throw out when you’re done using them.
Rigid lenses cover the pupil and the iris and are smaller than soft contacts. You’ll usually need to remove them at night, depending on the style you choose. Extended-wear rigid lenses are also available.
Implantable Contact Lenses require surgery. Your eye surgeon will implant an aphakic IOL (intraocular lens) between the iris and your natural lens. Another kind of ICL is positioned between the cornea and the iris. These lenses can be removed if needed.
Overnight contacts for myopia work the same way as orthokeratology contact lenses for astigmatism. They are worn only at night, and you’ll see clearly throughout the entire day. You have to wear ortho-k contacts every night to maintain your vision.

Myopia Corrective Eye Surgery

The only permanent treatment option for myopia is refractive surgery. Options include:

Custom LASIK surgery (laser-assisted in-situ keratomileusis) corrects myopia and other refractive errors. It works the same way as LASIK for astigmatism.
Photorefractive keratectomy (PRK) is less invasive and is performed directly on the surface of the eye. It’s a good option if you have a thin cornea or dry eyes.
Refractive Lens Exchange (RLE) involves taking out your natural lens and replacing it with an intraocular lens implant (IOL). With RLE, you won’t have to worry about cataracts since the artificial lens will not deteriorate.

Coexistence of Astigmatism and Myopia

Having both irregular astigmatism and myopia is clearly not winning the vision lottery. However, these conditions can and do frequently coexist. If your cornea is too long and oddly shaped, symptoms may include blurrier vision than either of these conditions alone.

Here are some things to keep in mind if you have both astigmatism and myopia:

Prescription contact lenses or eyeglasses must correct for both conditions.
You may still notice some blurry vision, even when wearing your eyeglasses or contact lenses.
You may need to wear your glasses or contact lenses at all times for both near and distant vision.
Consider refractive surgery for a more permanent solution.

Lifestyle and Prevention Tips

You can sometimes prevent or slow the progression of astigmatism and myopia by following these tips:

Limit time on digital devices, taking frequent breaks.
Don’t read or work in dim light.
Go outdoors and expose your eyes to natural light and distant objects.
Wear sunglasses to block harmful UVA and UVB rays.
Eat healthy foods that provide your eyes with essential nutrients.
Schedule regular eye exams to prevent or detect any vision problems.

Visionary Eye Doctors provide LASIK and other refractive surgeries as well as prescriptions for eyeglasses and contact lenses. Contact us today for assistance overcoming myopia and astigmatism and restored vision.

Colorblind Glasses & Contacts

December 20, 2021/in General Optometry /by Carolina Clavijo

Those living with colorblindness, or color vision deficiency, face challenges in everyday activities that most people take for granted. The inability to differentiate colors has a constant impact from driving to shopping for clothes.

While there is no cure, visionary experts have developed a new way to alleviate the condition. Keep reading to learn how innovative glasses and contacts are changing the way the colorblind see the world.

Different Types of Colorblindness

Generally, an inherited condition, colorblindness affects an estimated 300 million people worldwide. There are seven different types, but red-green colorblindness is the most common form. Many colorblind people also have trouble seeing blue and yellow, and in extreme cases, no colors are seen at all.

The trouble differentiating between colors often results in people developing their own ways of compensating, whether by telling them apart by brightness, timing, location, or even using an app. But now, researchers have come up with a far more accurate and practical solution.

New Options for the Colorblind

Colorblind glasses have specially tinted lenses that help a colorblind person see colors more accurately. The tints are based on the type and level of colorblindness. For example, red-tinted glasses can aid in distinguishing between shades of red and green. They tend to be bulkier than your average reading glasses and can come in both prescription and nonprescription lenses.

Another option is innovative contact lenses infused with gold — yes, gold! Gold nanoparticles help scatter light and are used in various ways across biomedicine and technology. In this case, tiny gold particles are mixed with a hydrogel polymer (a soft and flexible material ideal for contact lenses) to create rose-tinted molds that filter light when red and green overlap.

Both gold-infused contacts and tinted glasses can provide similar levels of effectiveness.

How They Work

Cone photoreceptors within the eye’s retina are what make color vision possible. Abnormal overlapping response to light by different cone cell types (those usually sensitive to red or green lights) causes most color blindness.

To offset this abnormality, colorblind glasses filter wavelengths of light where the overlap occurs. This allows the brain to distinguish red wavelengths from green more accurately, thus resulting in better color perception.

It’s important to understand that colorblind glasses are not a cure, nor do they entirely create normal color vision. But they can allow individuals with color impairments to see colors they’ve never seen before through revolutionary technology.

Visionary Eye Doctors is proud to offer options for our colorblind patients and is committed to educating the community on evolving treatments. Keep updated with our blog for the latest industry news and visionary advancements. You can also schedule an appointment online.

Debunking Contact Lens Myths

October 29, 2021/in General Optometry /by Carolina Clavijo

Imagine a life without glasses: no foggy lenses, no stopping to take them off before a workout, and no anxiety about losing or breaking them. If you wear glasses, you probably agree that those benefits sound pretty good! However, some common myths about contact lenses might be keeping you from making the switch to a simpler form of vision correction. Let’s delve into these misleading myths and learn why contact lenses just might be the change you need.

Myth 1: I’m too old for contact lenses

The only age restriction for contact lenses is whether you’re old enough. In the past, older adults were told not to wear them due to their higher likelihood of suffering from dry eyes or presbyopia (also called aging eye condition). The materials that contact lenses were made from in the past could make these conditions worse. Contact lenses are now made from a variety of materials, and your eye doctor can help you choose the best option for any eye condition you may have. These days, there are contacts specifically made for people who suffer from dry eyes. Some of them even contain added fluid to help moisturize your eyes, which helps to relieve the symptoms of dry eye.

Myth 2: Contact lenses can get stuck behind your eye

This is a scary one! Fortunately, it is not physically possible for a contact lens to get behind your eye. Our eyes are covered by a membrane that connects to the back of our eyelids to prevent anything from going behind the eye. If you can’t find your contact lens, it is most likely hiding under your upper eyelid. A contact lens can get “stuck” in your eye, but it is usually a soft lens and it cannot possibly migrate behind your eyeball. Adhering to proper guidelines for wearing your contact lenses will prevent them from getting stuck.

Myth 3: Contact lenses are too expensive

There are many options when purchasing contact lenses, and you should be able to work with your eye care provider to find one that fits your budget. If you have vision insurance, your policy may cover some or all of the cost of contacts, so be sure to call your insurance company for information. It’s also important to note that glasses require a large upfront investment, while contact lenses are generally a small monthly expense. While the annual cost of contact lenses might be slightly higher than that of glasses, many patients are willing to pay the difference for the freedom that contact lenses offer.

Myth 4: Contact lenses are a lot of trouble to take care of

Modern contact lenses require far less care than their predecessors. For minimal care requirements, you can choose daily disposable contact lenses, which require zero care. Even if you choose reusable contact lenses, most types can be cleaned, disinfected, and stored with one bottle of multiuse contact lens solution. Your eye care provider should instruct you on how to care for the type of contact lenses you choose. Eye infections can be easily prevented by following all instructions for the correct cleaning and storage of contact lenses.

Myth 5: Contact lenses are uncomfortable

While many contacts made 40 to 50 years ago were uncomfortable, modern contact lenses are thin, flexible, and soft. In fact, after a brief adjustment period, most people get so comfortable that they don’t even remember that they are wearing them! If you still experience discomfort after the adjustment period, there are several remedies that can help once your eye care doctor pinpoints the exact cause.
